WATER-HEATER WITH GARBAGE-BURNER.

SPECIFICATION o ing pa o e e Patent O- 787,176, dated April 11, 1905.

Application filed July 12,1904. Serial No. 216,205.

be it known that I, .\Iicu.\ui. I IIi-nnn-nrr, a citizen of the I'nitedStates, residing at Chicago. in the county of (look and State ofIllinois, have invented a new and useful Improvement in\Vater-IItaitei-s with Garbage-Burners. of which the following is aspecilication.

My invention is in the nature of a novel form of furnace designed moreparticularly for a water-heater and so constructed as to permit of theeconomical disposition and utilization of garbage in connection withother fuel.

It relates to that form of furnace in which a second supplementary grateis employed above the usual lire-chamber; and it consists in the novelcombination and arrangement of parts whereby either garbage or soft coalmay be burned on this supplementary grate with a complete combustion andwithout the, produc tion of bad odors and securing at the same time aneconomical and efficient water-heater, as will be hereinafter fullydescribed with ref erence to the drawings, in which' Figure I is a sideelevation of the furnace. Fig. 2 is a vertical longitudinal sectionthrough the same. Fig. 3 is a vertical cross-section talten on the line3 3 of Fig. 2, and Fig. I: is a perspective view of the principal partsof the furnace with the outer casing removed.

In the drawings, Figs. 1 and 2, X represents the furnace-walls or outercasing. II is the ga rbage or soft-coal door: I, the hard-coal door; .1,the ash-pit door, and K clean-out doors at the side.

The principal parts of the furnaci are seen in Fig. i, and they comprisea flat horizontal waterchamber A at the top forming a complete roof tothe tire-space and two horizontal water-pipes A A at the bottom. Thesepipes at their front portion are connected directly to the topwater-cliamber by vertical circulation-pipes A". which lie along thesides of the upper and lower lire-chambers. The

rear portion of the pipes A A and chamber A are connected throughIlatand hollow \vater-boxes I) I) I)" I). which are arranged verticallyin parallel position toeach other. These water-boxes form hollowvertical partitions extending transversely across the furnace, but

have a free space above and below them. lhrough the upper free spaceshort vertical pipes c w connect the water-boxes to the upperwater-chamber A, and through the lower free space corresponding pipes1/1! 11* connect the water-l. o.\'es to the two subjacent water-pipes AA, so as to permit an upward circulation of water from the pipes A Athrough the hollow partitions to the alterchamber A above.

C is the main or hard-coal grate, made, as usual, of rocking bars, asseen in Fig. 23, and connected in the ash-pit by a coupling-bar 1', bywhich they may be all rocked together by a suitable handle /1, appliedto the squared end c, Fig. I, of one of the grate-bars.

I and IC are baIlle-plates arranged in the bottom of the rear part ofthe furnace. The plate I directs the air from the ash-pit up through thegrate C and shuts off the space in rear of this plate. Said plate I alsoforms a bearing-support for the rear ends of the rocking grate-bars. Theother batIle-plate, IQ, extends from the bottom of the furnace to thebottom of the hollow partition If. At the upper ends of the hollowpartitions I) and I) are arranged dampers F F, whose shafts are extendedthrough the side walls of the furnace and provided with crank-handles f,by which the positions of these dampers may be adjusted. \Vhen thedampers are turned vertically, as shown in Fig. 2, a tortuouspassage-way is provided for the products of combustion around andbetween the hollow partitions, as shown by the arrows; but when, as inlirst building the lire, the dampers are turned down, as shown in dottedlines in Fig. I and full lines in Fig. I, the products ofcombustion passdirectly from the top of the partition I) to the smoke-pipe- (I.

About midway the space between the grate and the top water-chainber A islocated the supplementary garlmge-grate I This is cast in one piece,with hollow bars and end chambers, the end chambers being provided withdetachable screw-plugs in line with thehollow bars, so as topermitsedimentto becleaned out from the same. 'lhe frontend of thishollow grate (see Figs. 2 and I) is connected to the two subjacentwater-pipes A A by means IOC of standing vertical circulation-pipes 6along the sides of the fire-chamber and in the plane of thecirculation-pipes A The rear end of this hollow grate is connected bysuspended pipes b with the hollow water-chamber A at the top, and thesepipes are likewise arranged at the sides of the upper fire-chamber andin the plane of the other circulation-pipes, A

The two sets of pipes 7) and Z) serve to hold the hollow grate B inhorizontal position above the main grate and also form circulation-pipesfor this water-grate, the colder Water rising through the pipes b to thewatergrate and after traversing the same and becoming heated passes,from convection, upwardlythrough the pipes b to the top water-chamber A.

The position of the hollow grate B holds the garbage above the tire, sothat the flames, the air, and products of combustion circulate throughand around it, simultaneously cre- Inating it without objectionableodors and also utilizing its combustible elements to increase thefuel-supply and economically heat the water.

The colder return water of the water-heating system enters the bottompipes A through the smaller pipe a, and the heated water passes out fromthe top water-chamber A through the issue-pipes a a to the various pipesleading to the radiators of the system.

Instead of using garbage on the elevated water-grate B wood, sawdust,soft coal, or any other similar fuel which requires a large access ofair for its combustion without smoke may be successfully burned.

I do not claim, broadly, an elevated supplementary grate, as I am awarethat this is not broadly new.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A water-heating furnace, comprising upper and lower water-chambers, amain grate cal circulation-pipes arranged at the side of the two gratesand connecting the upper and lower Water-chambers substantially asdescribed.

2. A water-heater having tWo grates, the upper one being a water-grateconnected, for circulation, with the water-spaces and having in rear ofthe same hollow upright partitions also connected, for circulation,withthe waterspaccs and having dampers above and battleplates belowsubstantially as and for the purpose described.

3. A water-heating furnace comprising u pper and lower Water-chambers, amain fuelgrate and a water-grate located above the main grate andformedin one-piece and provided with clean-out plugs in its end and combinedwith and exclusively supported by standing circulating-pipes at itsfront end connecting with the lower water-chamber and by suspendedcirculation-pipes at its rear end connecting with the upperwater-chamber substantially as and for the purpose described.

4. A Water-heater having two grates, the upper one being a water-grateconnected for circulation with the water-spaces and having in rear ofthe same hollow upright partitions also connected for circulation withthe waterspaces and means for causing the fire-currents to circulatebetween the hollow" upright partitions substantially as described.
